RAP – The Trading Edition™ Basics

RAP – The Trading Edition (RAP) is a consolidated trading and risk data repository and data services platform for customers in the capital markets and investment management sectors.

RAP consolidates market data from vendor feeds, historical time series data, real-time trades and quotes (TAQ) data, and reference data in one repository, which eliminates or reduces intraday and overnight batch processing, and supports model-driven quantitative trading and real-time portfolio decisions by presenting subsets of data to various applications.

• Platform Architecture
  The RAP architecture includes feed handlers, publishers, subscribers, and data stores.
• Operations Console
  The Web-based Operations Console lets you monitor system activities, administer data transfer and truncation policies, and perform system configuration and routine administration tasks.
• Feed Handlers
  Feed handlers manage data that arrives directly from an exchange, like the NYSE, or a consolidated service provider, like Reuters. Using the publisher API, the feed handlers then send the data over the network to one or more subscribers.
• Subscribers
  When a publisher sends a message, subscribers receive the message and load it into the appropriate data store.
• Data Stores
  RAP data stores include an in-memory cache (or alternatively, relaxed durability disk-resident) database that provides immediate data access, and a historical repository that can manage historical and corporate reference data sets.
• Network Communications
  UDP is the mechanism that lets publishers and subscribers exchange packets of data, called datagrams.
